CrowdStrike shares fell 13% in trading sessions during the course of how the cybersecurity software company continued to help customers in all sectors to come back on track following an interruption that resulted in many Microsoft Windows computer systems to be down for the entire week.

Early on Friday, the company issued a defective update to its Falcon vulnerability-protection software that caused PCs, computer servers in data centers and display screens to crash, resulting in grounded flights and canceled medical appointments. The glitch affected 8.5 millions Windows devices, which is less than 1percent of the amount, Microsoft said.

IT staff quickly began fixing computers fast. While they were fixing computers on the computers, hackers tried to take advantage of the chaos by launching fraudulent websites that appeared to offer upgrades to the applications. CrowdStrike President George Kurtz discussed the issue in an interview to CNBC’s Jim Cramer.

CrowdStrike shares fell by 11 percent over the course of Friday. However during the weekend, users posted pictures on social media of Windows devices which showed”blue screen of death. “blue screen of death,” a sign that computers need attention from admins. CrowdStrike declared on Sunday that it was testing with a method of fixing damaged devices faster.

Guggenheim Securities downgraded its rating on CrowdStrike shares to neutral from buy on Sunday. Analysts under the direction of John DiFucci said the stock was traded at “the the highest ratio of the recurring revenue across our complete software coverage. “

It could take some time required to allow CrowdStrike to improve their image. The resulting damage could influence the signing process, according to analysts. Signings are the first estimation of the worth of contracts signed by customers that are new or already in place. These can give investors a sense of the company’s capacity to earn revenue.

“We still have the utmost respect for the leadership team at CrowdStrike and believe that the company will eventually become even stronger as a result of this incident, and if investors have a multi-year horizon, they can ride it out,” they said. “However it is difficult to inform investors to purchase CRWD immediately. “

Goldman Sachs maintained their purchase rating on CrowdStrike shares, in a report that was released earlier on Monday. However, analysts at the investment bank stated that they had anticipated that the transactions of CrowdStrike will be delayed between the time of the outage to July 31, which is the close of the fiscal second quarter.

“Our recent conversations reaffirm our view that there will likely be minimal share shifts in endpoint post this event — although we recognize that additional details in the postmortem will further inform this view,” analysts led by Gabriela Borges wrote.

They also mentioned an older McAfee glitch that led to computer crashes in order to give glimpse of what transpired prior to the last week.

“The revenue impact due to deferrals was about $6 million of deferred revenue not recognized from the balance sheet, and revenue was also negatively impacted by another approximately $14 million,” then-CEO Dave DeWalt told analysts in July of the year before during an analyst phone call. Kurtz was chief technology director of McAfee at the time.

In just one month, after the McAfee earnings conference, Intel announced that it would purchase the antivirus company for $7.7 billion.

“This is an evolving situation,” CrowdStrike declared in a regulation form that was filed on Monday. “We are continuing to assess the impact of this event on our operations and business. “
